What 'Verified' Actually Means on CallForPaper.org

If you’ve browsed conference listings on CallForPaper.org, you’ve probably noticed a small badge next to some conference names: Listed, Verified, or Trusted. I get asked fairly often what these actually mean — whether “Verified” means we’ve checked that a conference is legitimate, whether it’s safe to submit a paper, or whether it’s just a checkmark organizers pay for. I wanted to write this down properly, once, so there’s a single place to point people to.

This article is meant to be the hub for everything we’ve published on how conference and journal verification works on the platform. I’ll link out to the deeper technical write-ups as they come up.

The three statuses, in plain terms

Every conference or event listing on the platform sits in one of three states:

Listed — The event has been added to the platform, either submitted by an organizer or picked up automatically from a public source (conference websites, society calendars, RSS feeds, and similar). At this stage we haven’t done anything beyond publishing the basic details: title, dates, location, and submission deadlines. A “Listed” conference isn’t flagged as a problem — it simply hasn’t gone through any additional check yet.

Verified — An organizer has claimed the listing through our claim-link process and confirmed the core facts of their own event: that the listing is accurate, that they are actually affiliated with the conference, and that the details (dates, venue, submission process) are current and correct. Verification is fundamentally an organizer-confirmed accuracy status, not a third-party legitimacy audit. It tells you “the people running this event have taken ownership of this listing and stand behind what’s written here.”

Trusted — This is the status reserved for events where we’ve been able to independently corroborate claims that go beyond what the organizer alone tells us — things like a stated society affiliation (IEEE, ACM, Springer, Elsevier), indexing claims (Scopus, Web of Science, IEEE Xplore, DBLP, Crossref), or a track record across multiple past editions of the same series. Trusted status is harder to earn and takes longer, because it depends on matching what an organizer says against outside records rather than taking a claim at face value.

You can think of the three as a ladder: Listed → Verified → Trusted, each step adding a different kind of evidence rather than just a different level of “how good” the conference is.

What “Verified” checks — and what it doesn’t

This is the part that trips people up, so I want to be direct about it.

Verified confirms:

• The person or organization behind the listing actually controls it (via our tokenized claim-link flow)
• The stated dates, deadlines, and venue are current and accurate
• Contact details for the event are reachable and belong to the organizer

Verified does not by itself confirm:

• Whether a claimed society affiliation (e.g., “an IEEE conference”) is genuine
• Whether the proceedings will actually be indexed where claimed
• Whether the conference or its organizer has a track record of predatory behavior elsewhere

Those checks exist too, but they live under the Trusted tier and our separate indexing-status and affiliation-verification work, not under basic verification. We keep these layered on purpose: an organizer confirming their own listing is a low bar that almost any legitimate event should clear quickly, while affiliation and indexing checks require corroborating outside sources and naturally take longer. Collapsing the two into a single badge would make “Verified” mean too little for events that deserve more scrutiny, and too much for events that just haven’t gotten around to claiming their page yet.

If you want the detailed walkthrough of how we approach affiliation claims specifically — including what we look for when a conference says it’s “IEEE” or “Springer” without that being straightforwardly checkable — I wrote that up separately: How We Verify IEEE & Society Affiliation Claims, based on a review of over 400 conference listings.

How an organizer moves from Listed to Verified

When a new conference is added to the platform, we look for a public contact for the organizer and send a claim email with a single link. Clicking it brings the organizer to a dashboard where they can edit and confirm their event’s details — that action is what moves a listing from Listed to Verified. If a listing is claimed but sits unverified for a few days, we send a follow-up nudge; verified organizers with strong listings later get an invitation to consider featured placement.

There’s no fee to verify a listing, and it isn’t gated behind a paywall — it’s simply the organizer confirming their own event is accurately represented.

Why we separate “unverified” from “predatory”

One thing we’ve been deliberate about: Listed does not mean warned, and unverified does not mean predatory. The overwhelming majority of academic conferences are legitimate, ordinary events run by people who just haven’t clicked a claim link yet. We don’t want the absence of a badge to read as an accusation.

Separately from the badge system, we also maintain an open-source, evidence-backed dataset of organizers and conferences with documented predatory patterns, released under CC0 so anyone — researchers, other platforms, journal indexers — can use it freely. That dataset feeds into our internal review process, but it’s a distinct signal from verification status, and we keep it that way intentionally.

Indexing status and other trust signals

Beyond the badge itself, individual conference listing pages show additional context where we have it — including an indexing status panel (Scopus, Web of Science, IEEE Xplore, DBLP, Crossref) and, for journals, results from our ISSN-checker tool, which pulls publication history and journal data from sources like OpenAlex, DOAJ, and Crossref so you can see a journal’s track record in one place rather than hunting across five different databases.

Each of these is its own signal, shown alongside — not folded into — the Listed/Verified/Trusted badge, so you can see exactly which claims are organizer-confirmed and which are independently corroborated.

The short version

• Listed: added to the platform, unclaimed, not yet reviewed by the organizer
• Verified: the organizer has claimed the listing and confirmed it’s accurate
• Trusted: claims like society affiliation or indexing have been independently corroborated, not just self-reported

If you’re an organizer and your event is sitting at “Listed,” claiming it takes a couple of minutes and is the fastest way to get it to “Verified.” If you’re a researcher trying to sanity-check a call for papers before submitting, I’d treat the badge as one input among several — read the indexing status, check the ISSN-checker report if it’s tied to a journal, and compare it against our predatory-conferences dataset if something feels off.

I’ll keep updating this page as the Trusted-tier checks (affiliation matching, series/recurrence detection) mature — for now, consider it the map for how the rest of the trust-and-verification content on this blog fits together.
